Question

A cube of ice is taken from the freezer at -8.5 ∘C and placed in a 85-g aluminum calorimeter filled with 320 g of water at room temperature of 20.0 ∘C. The final situation is observed to be all water at 15.0 ∘C. The specific heat of ice is 2100 J/kg⋅C∘, the specific heat of aluminum is 900 J/kg⋅C∘, the specific heat of water is is 4186 J/kg⋅C∘, the heat of fusion of water is 333 kJ/Kg. What was the mass of the ice cube?

A major source of heat loss from a house in cold weather is through the windows. Calculate the rate of heat flow by conduction through a glass window 2.0 m × 1.5 m in area and ℓ = 2.8 mm thick (Figure 1), if the temperature at the inner and outer surface is 15.0∘C. Assume that there are strong gusty winds and the external temperature is 0.0 ∘C .

A cube of ice is taken from the freezer at -8.50 oC and placed
in an 85 g aluminum calorimeter filled with 310 g of water at room
temperature of 20.0°C. The final situation is all water at 17.0°C.
What was the mass of the ice cube in gram? (Lf = 3.3x105 J/kg,
cwater = 4186 J/kg.C, cAl = 900 J/kg.C, and cice = 2100 J/kg.C)

Chapter 18, Problem 041
(a) Two 58 g ice cubes are dropped into 410 g
of water in a thermally insulated container. If the water is
initially at 20°C, and the ice comes directly from a freezer at
-11°C, what is the final temperature at thermal equilibrium?
(b) What is the final temperature if only one ice
cube is used? The specific heat of water is 4186 J/kg·K. The
specific heat of ice is 2220 J/kg·K. The latent heat of...

I place an ice cube with a mass of 0.223 kg and a temperature of
−35°C is placed into an insulated aluminum
container with a mass of 0.553 kg containing 0.452 kg of water. The
water and the container are initially in thermal equilibrium at a
temperature of 27°C. Assuming that no heat enters
or leaves the system, what will the final temperature of the system
be when it reaches equilibrium, and how much ice will be in the
container...

A 25 g ice cube at -15.0oC is placed in 169 g of
water at 48.0oC. Find the final temperature of the
system when equilibrium is reached. Ignore the heat capacity of the
container and assume this is in a calorimeter, i.e. the system is
thermally insulated from the surroundings. Give your answer in
oC with 3 significant figures.
Specific heat of ice: 2.090 J/g K
Specific heat of water: 4.186 J/g K
Latent heat of fusion for water: 333...
